When data link tables are generated automatically, data link status is output to
SR 238 through SR 241 for the operating-level-0 data link. And to SR 242
through SR 245 for the operating-level-1 data link.
Each of the above sets of four bits contains the four flags indicating data link sta-
tus for a node, as shown below.
error has occurred.
Any of the above bits that are not used by the System (i.e., those bits assigned to
node numbers beyond the possible range) can be used for work bits.
When data link tables are generated manually, data link status is output to con-
secutive words starting with the beginning status word designated in the refresh
parameters. Data status is only available for the nodes designated in the refresh
parameters, i.e., the nodes from which link data is being received. In the follow-
ing table “m” is the beginning status word.
The actual link status table will be only as long as required to store the status of
each node for which there is a link (see Example , below. Each of the above sets
of four bits operates as shown below.

Turned ON to indicate the PC is in RUN or
MONITOR mode. OFF indicates
PROGRAM mode.
Turned ON to indicate the PC has stopped
because of a fatal error.
Turned ON to indicate that there is a
communications error (time out), that the
Unit is not part of the System, or that the
data link is not active.
Turned ON to indicate the node is part of
the data link. OFF indicates that the data
link tables of the start-up node do not
match, or no operation is possible because
the data link table has not been created.
